title: "Does any implicit-neural-representation paper actually cite fractal/IFS/WFA image compression — is the 'image as a compact function' lineage real or only a structural rhyme?"

[[claim-fractal-compression-to-implicit-neural-representations-bridge]] is flagged
`[unverified-claim]`. It asserts that fractal / iterated-function-system image
compression (Barnsley, Iterated Systems Inc., 1987) and 2020 implicit neural
representations (SIREN, NeRF) are the same recurring idea — "encode a signal as a
compact function, not a grid of samples." No source draws this line; it is Seek's own
synthesis. This question routes the verification that would either graduate the note
or keep it a rhyme.

**What would answer it:**

- **Find a direct citation.** Search the implicit-neural-representation literature
  (SIREN, NeRF, and their descendants) for any explicit citation of, or acknowledged
  debt to, fractal/IFS or weighted-finite-automata image compression. Even one
  load-bearing citation would turn the rhyme into a documented lineage. An exhaustive
  empty result is itself the sharper finding (independent reinvention of the same
  premise).
- **Pin the formal relationship.** Clarify how Karel Culik II's weighted-finite-
  automata (WFA) image compression relates to Barnsley's iterated-function-system
  (IFS) compression — genuinely distinct formalisms, or two encodings of the same
  object? (Left open as a "further lead" in the source capture.)
- **Firm up the fractal-compression history on better than Tier 4.** The setup facts
  (Iterated Systems founded 1987; commercial arc through products like Encarta; the
  ~2016 abandonment of the fractal-video successor; the encode≫decode cost asymmetry
  that kept it niche) currently rest only on Wikipedia (Tier 4), recorded for dates,
  not for any compression-ratio numbers. A primary or strong-secondary source would
  let the historical setup stand on its own.

This connects to the vault's image-compression cluster
([[claim-djvu-1998-paper-coauthored-by-lecun-and-bengio]],
[[claim-internet-archive-2016-stopped-generating-djvu]]) and to
[[claim-siren-2020-implicit-neural-representations-signals-as-functions]]. Resolving
it lifts (or hardens) the flag on the bridge note.
